The best pitcher in baseball from 2008 to 2011, two-time Cy Young winner Roy Halladay called it a career on Dec. 9. Halladay pitched a perfect game and also a postseason no-hitter, but never made it to the World Series in his 16-year career with Toronto and Philadelphia. His 2012 and 2013 seasons were plagued by shoulder problems that led to drops in velocity and effectiveness. He was 203-105 with a 3.38 ERA in 416 career games, including 390 starts. He had 67 complete games and 20 shutouts. His resume includes three 20-win seasons, eight All-Star games, and three other top-3 finishes for the Cy Young Award.
